fg. 8 iS a top view of the suppoft taken on line 88 of ig. 7. ig. 9 is a fragInentafy Sectional view of al Inodiffed fofm of suppoTt embodying a jaok.

Fig. 10 is a fTont vieW of another n1odied fofm of suppoft.

,ig. 11 is aJ Side view of the support and Inount 10 ing, indioating the mode of opeTation, and shoW ing a bumpeT.

Referring Inore paftioulofly by nuInefals to the drawings, in Whioh the Same and Sin1ilaT e1e fnents afe designated by 1ike SyInbolS of fefefenco 15 throughout, and Inofe espeoially to Fig. 1, thefe is shown an axle of al vehicle having steering WheelS 2 and 3 n1oonted thefeon. The wheels afe adapted to be turned in the oonventiona1 Inanner through actuation of a steering aTn1 4 fixed. of1 an arn1 5 operating vith the whee1 3 and conneoted to o sin1ilar arn1 9 on the whee1 2 thfough tie rod 2.

n nlaneuvering in and out of a Test1'icted pafk ing afea it iS uSuany neceSSaTy to tufn the Steering vvheelS of a vehiole sevefa1 tin1eS vvhile the vvhee1S afe at feSt. T1iS iS a difficult and tifing task, as unless a vef1icle is Inoving it is hard to tufn the vvhee1s.

In fny Several applioationS alfeady refeTfed to have diSo10Sed devices fof ovefooIning thiS diffi oulty. TheSe devioeS afe in the natufe of sup pofts foT optiona1 uSe Whereby the steeTing vvhee1S of 3, vehiole nlay be elevated of the vveight of the vehiole thereon Telieved to a Suffiofent de gree to anow easy tufning of the wheels.

The SuppoTtS genefally have been pivoted to the end of the vehiole caffying the steefing WheelS for SWinging backwafd and forWard, Whefeby on baokwafd of fofward Inovefnent of the vehiole the end theTeof ooffying the suppoft is adapted to fide upon the suppoft. While the support Inay be of soch aJ length as to pfovide foI' elevation of the Steering wheelS to any degree, it iS genefany deen1ed suffioient to Inerely provide dt5 foI' felieving the vveight on`the steefing vvhee1S to a s11fiicient degTee for ar11ovving ffee tuTning of the Whee1s. In tl1is oonnection a jaok Inay be en1bodied in the Suppoft to provide fof fufthef elevation of the wheelS When an end of a vehicle is esting on the Support, of the support Inay be Inade oxtenSible and fetfactable.

The support diso1osed herein ooInpTises a, bar 9 adapted to be mounted on the underside of the ax1e l acToSS the longitudinal axiS of a vehicle. 'f1e endS of the balI' 8 afe extended thfough apeT- tufes pTovided in beafing b1ookS 9 and l9. T21e baf 8 iS adapted to S1ide aS vve11 aS fotte in the beaTings 9 and ln. The beafing blocks nlay be seoured to the axle in any Suitable Inanner, fof exaInple by U bolts l extending thfough feoeiv ing lateS 2 and oxed by notS 3. The beaTings nlay be provided With V ohannels 4, as shown in ig. 2, for Teceiving a portion of the axle, of othefvvise oonStfucted to acoon1fnodate diffefent 65 fofInS of axles.

In f ig. 2 there is also shown a conventional Spfing 5 xed acfoss the axle by U boltS l5 in the usual n1anner and hoving the endS seoued to a ffame member fhe bar 3, as is better shown in 'ig. 3, is adapted to extend through T n1efnbefS !8 and l9 spaced and poSitioned on each side of the cen tef of the bof ond fixed thefeto fof exanlple by ve1ding, aS indioalted at 29. 1e angulof pfojeotions on the T1 leInbers aTe interna11y threaded fof feoeiving the top endS of baTS 2 and 22, oppositely thfeaded at eaCh end 9JS at 23 and 22. The lower ends of the barS 2l and 22 afe odapted to engoge in thfooded apeftufes provided on each end of al ofoss plate 25.

The plate 25 is futthef pfovided vvith a oentral apeftufe for feoeiving a bolt 29 having the body portion 2T thereof adapted to fotate in the apert11fe, and pfovided vrit11 an integfal1 thfeaded ex tension 28 foI' soreWing in a oentfal tl1feaJded apeftufe 29 pfovided in a, pear Shaped suffaoe contact Inen1ber 39. The thfeaded extension 28 on the bolt iS fixed to the Sufface oontact fnen1ber 39 by a 1ock Wahef 3l fitted in a reoeSS pfovided in the top of the contaot IneInbef.

The baTS 2l and 22 afe xed with respeot to the T Inen1beTs i8 and 9, and the ofoss plate 25 by look nutS 32. It vvi11 be appfeoiated that the suppoft structufe fnay be extended of' fetracted by unsofewing the nuts 32 and rotating the barS 2 and 22, the endS of Which, aS alfeady pointed out, are oppositely threaded,

t Tvi11 be paftioulafly noted that the oontact IneInbef 39 vvhioh is ffee to fotate With the bolt 25, With respect to the plate 25, has an extended sofface contact area 33. The contaot n1en1bef is pfeferably conpoSed of fneta1, but may be seInihafd rubbef oI, any other Suitable Ina teTiaL of may be composed of Inetal and pfovided with a rubbef Shoe.

The bar 9, aS already pointed o11t, iS free to fo tate in the beafingS 9 and l9, caTrying the memberS l8 and l9, bafS 2l and 22, plate 25 and contaot n1eIT1bef 39 thefevvith, The baf 8 iS also ffee to slide in the beafingS 9 and 9. The bar 9 iS nornlaHy held oentered hovvevef by helioa1 Springs 3 and 32, enciroling the bar and abut ting against the beaTings 9 and T9 and T fneIn befs I8 and l9.

TT1e support is adapted to be lowered and faised by a cable, as shown in igs. 1, 2 and 3, attaohed to one end of the plate 25 by a bolt 35 extending thfough an eyelet 39 fixed on the end of the Cable, and a WaShef 37, and having a feduced threaded extenSion 39 fof engaging in a thfeaded apefture in the end of the plate. T21e oable may be enolosed in a conduft 39 and the cable of con duit, of both, poSitioned in any suitable Inannef.

vvhen it is desired to eInploy the suppoft, the Stfuoture is 1ovvered froIn the nofnlany raiSed po sition, as indicated in 1='ig. 11, fof ffee Svvif1gif1g n1oveInent, by releaSe of the cable designated by the ntIn1efa1 39. The end f the vehfCle caf1 ying the Suppoft is adapted to fide up thereon, by backWard of fofwafd n1oveInent of the vehicle, vvith swinging of the Suppoft aofoss the vertioa1, the oontact n1efnbef 39 engaging the foad sufface to enable ffee tufning, When InoveITlent of the vehicle is continued to fide off the Suppoft, and the operation fepeated TevefSely. The Suppoft is nofn1any held up in inoperotive poSitfon by xing of the oable 39, in the opefating coInpart- II1ent of the vehicle. In oTdef to pfevent fattling an adjustably tensioned plunger 3o Inay be Inounted on the oxle, for example by a olaInp, and the Support held thefeagainSt by tighte1iI1g of the cable 39. Pull fofceS exefted. on the oable are thus cofnpensated foI' When the vehfole Inoves With fespeof to the axle on the Spfings.
